Abstract :
Iron films with different thickness were prepared on glass substrate by DC magnetron sputtering. Arrays of α-Fe2O3 nanowires and nanosheets were grown on iron films by thermal oxidation. The morphology and structure of the prepared α-Fe2O3 nanostructures were characterized by SEM, XRD, XPS, Raman and HRTEM. Field emission properties including I-V characteristics, emission uniformity and stability are studied. The relationship between the field emission properties and parameters of α-Fe2O3 nanostructures is discussed.
